d00afc912c decoder/mad: eliminate the loop in SubmitPCM() 
libmad has a hard-coded maximum PCM buffer size; if we make our
output_buffer just as large, we can avoid the loop, because any
possible size will fit.

952c793235 decoder/mad: subtract libmad decoder delay from LAME encoder padding 
Apparently, libmad not only inserts 529 samples of silence at the
beginning of the file, but also removes them at the end.

This solves the last piece of

3e3d8c7f9d decoder/mad: pad the input buffer with zero bytes and end of file 
libmad requires padding the input buffer with "MAD_BUFFER_GUARD" zero
bytes at the end of the file, or else it is unable to decode the last
frame.

This fixes yet another bug which prevented this plugin from decoding
the last frame, see

9b99a9897a decoder/mad: don't count the Xing/LAME metadata frame 
The Xing/LAME frame indicates how many frames there are, but that
excludes the initial Xing/LAME frame.  Therefore, it should not be
counted.

This fixes an off-by-one bug which caused the last frame to be
skipped, fixing one part of

af99f9fc90 pcm/Volume: convert S16 to S24 to preserve quality and reduce noise 
Applying software volume to S16 samples means several bits of
precision are lost; at 25% volume, two bits are lost.  Additionally,
dithering adds some noise.

The problem gets worse when you apply the software volume code twice:
for the software mixer volume, and again for the replay gain.  This
loses some more precision and adds even more dithering noise, which
can become audible (see
https://github.com/MusicPlayerDaemon/MPD/issues/542).

By converting everything to 24 bit, we need to shift only two bits to
the right instead of ten, losing nearly no precision, and dithering is
not needed.  Even if the output device is unable to play S24 directly,
we can convert back to S16 with only one stage of dithering.
